A new reducing agent (2j) reduced the enone (4) to give 15(S)-allylic alcohol (5a) with excellent regio-and stereoselectivity through a five membered ring transition state. Stereoselectivity of this reaction will be explained based on the LUMO of the enone moiety. The resulting (5a) was led to a car

In the title compound, [Ni(C 26 H 28 N 2 O 2 S 2 )], the three independent Ni II complex cations are conformational isomers. The Ni atom has a square-planar environment and is coordinated by two imine functions and two S atoms. The NiÐN and NiÐS bond lengths are in the ranges 1.893 (4)± 1.909 (4) an
## Abstract The copolymerizations of (__S__)‐1,2‐propanediyl and (2__S__,3__S__)‐2,3‐butanediyl bis(4‐vinyl‐benzoate)s (2a and 2b) (M~1~) with styrene (M~2~) were carried out using 2,2′‐azoisobutyronitrile in toluene at 60 °C. For the cyclocopolymer 3, the extent of cyclization of 3b is higher than
